- In claim two, states that one part of the electronic circuit level acts as a comparator for natural or environmental brightness, other part acts as a presence pulse generator, a third one for excitation timer for output circuit and a fourth one as excitatory for output element, that supplies voltage to the lamps in other indicator traces connected to the device.
- Other invention patent is ES 424804, which refers to improvement control circuits for turning on automatic lighting installations, the class comprising a relay to control charge for circuits lighting or piloting a switching contact thereof, characterized by the fact to perform said developer control excitation or pilot from the circuit output of control circuit, which comprises, in parallel, in parallel, a load line in which are included on series the excitation winding of said developer, the emitter collector circuit from a transistor in changeover function and stabilization and biasing resistor, a control circuit formed by two resisted variables sections whose midpoint is connected to the base of the transistor, one of whose sections comprises an adjustable resistor the other a bias resistor and a photo resist device, being the end of two parallel lines or circuits connected to the output of a power supply circuit, which comprises connectable to an AC network input terminals, this means AC converters on low DC voltage to power maneuver circuit.
- Even though existing devices or systems currently serving the proposed objectives, it is also true that are deficient, compared with the device of the invention, which presents the following advantages:
-
- This system is more efficient because it quantifies persons entering and leaving a room, to turn on the lights and counts down to zero to turn them off.
- It is cheaper and easy to install, can be sold in packs sold on retail companies know that any electrician would know to install.
- It requires less power to operate since it detects people in the door frame, instead others must cover the entire room.
- It is more efficient as the lights do turn off at being quiet people in a room.
- It is further technological, more advanced than other systems being able to control entire buildings with this device.
- To understand more clearly the invention, will be describe based on an exemplary embodiment, without this implying that the invention may be limited to this example or elements which may arise in obvious way, based on the drawings which form an integral part of this presentation, wherein:

- According to the brightness of the room or sun effect, infrared filter is installed (identical to dark plate at the front of some remote controls), this is to prevent interference with external infrared signals.
- According to the height of the door, using phototransistor (2) without lens detection range is approximately one meter, that is, placing it in a door of two meters, the proximity sensor (1) is capable of detecting people with a height greater than or equal to one point two meters. Using convex lenses in phototransistors (2) extends detection range up to five meters. Proximity sensors (1) consist of a transmitter (3) and one receiver (4) operating at the frequency supplied by the oscillator “LM567 (25)” as well as a semiconductors set to provide at integrated circuit and generally, the voltages required for correct operation of proximity sensors (1).
